ELECTRIC-LIGHT REFLECTOR AND ITS SUPPORT.

SPECIFICATION forming part of Letters Patent No. 254,523, dated March'7, 1882.

Application filed December 8,1881. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM WHEELER, of Concord, of the county ofMiddlesex and State of Massachusetts, have invented a new and usefulImprovement in Electric-Light Reflectors and their Supports orAttachments; and I do hereby declare the same to be described in thefollowing specification and represented in the accompanying drawings, ofwhich- Figure 1 denotes a side elevation, and Fig. 2 a top view, of acompound reflector provided with my invention, the nature of which isdefined in the claims hereinafter presented. Fig. 3 is an inner end viewof one of the reflectorsections with its clamps and binge portions, tobe described. Fig. 4 is an inner end view of the otherreflector-section, showing its hinge portions.

The reflector shown is of double formthat is, it is composed of twoseparate truncated or bonnet-shaped reflecting-sections, A B, arrangedwith their lesser ends or bases in contact. They are designed toreflectin opposite directions. rays or beams of light from an elec' tricburner arranged at or about at the center of their common intersection.There project from each of the sections, atits inner end, two ears, a ab b. These ears are provided with two sets of bin ge-j oint tubes, 00 dd d d, those marked 0 being projected from the ears of one of thesections, while those marked d extend from the ears of the othersection. Each ot'the tubes 0 is to go directly between and in line withtwo of the tubes d, and with such and a pin, 0, passing through thethree tubes, is to constitute a hinge.

Each ear of the section A has a clamp, O, hinged to it at its outeredge, such clamp and ear being recessed to receive and span acylindrical insulator, D, of india-rnbber or other suitable material,through which tube one of the two vertical rods forming a part of. theframes of the electric lamp, and used in this case for supporting thereflector also, is to pass. Each clampC is furnishedwith a screw, E,which goes through it and screws into the ear,

and is to set the clamp firmly to the insulating-tube, and that to therod. 7

Each reflector-section is notched at its lesser end, as shown atf, inorder that when the two sections abut against each other at their lesserends there may be a vertical passage through them to receive the carbonpencils or means employed in the reflector for generating the electriclight. On withdrawing either of the hinge-pins from its tubes thesection B may be turned on the other pin in a direction away from thesection A, in order for access to be had to the burner or partscomposing it, the two sections being fastened together when the two pinsare in place in the hinge-tubes.

In certain cases where the lightis to be projected in one directiononly, or when a double form of reflector, made in one entire part, is tobe used, only one ear is provided upon each side of the reflector, andhence the hingesjoining the two separable parts herein shown aredispensed with,the clamps remaining as shown and described.

'I would remark that the two sections, instead of being provided withtwo hinges to enablethem to be opened apart in either of two directions,may be hinged together so as to open apart in one direction only; but Iprefer to have them doublehinged, as described and represented, for insuch case either hinge, be-

sides serving the purpose of a hinge, answers WM. WHEELER.
